"Permanent subtitle" is called open caption, which is burned into the video and cannot be turned on or off by the user. Have you ever meet the need of adding subtitle to a video permanently? Such as, add permanent subtitle for a movie so you can watch it with subtitle on mobile devices, or some of the video players on the desktop are not allowed adding an external closed caption for a video. If this is your case, you will need a video file, a subtitle file for the same video, and a tool that can add subtitle to the video. In this article, I am going to teach you how to merge SRT/SSA/ASS subtitle into a video permanently in a fast way with software, which applies to use on Mac/Windows computer.

Part 1. The Difference between SRT/ASS/SSA Subtitles

SRT, ASS and SSA subtitles are the three most commonly used subtitles.

• SRT

SRT is the abbreviation for SubRip Text. This is the simplest text subtitle format that consists of a numeric counter, the time and the subtitle text itself.

• SSA

SSA stands for SubStation Alpha. It's more powerful than SRT. It supports various colors, fonts, and other special effects.

• ASS

ASS means Advanced SubStation Alpha. It includes all the features of SSA and extension based on the original features of SSA.
